预算约束下的近可行稳定匹配

Near-Feasible Stable Matchings with Budget Constraints

Yasushi Kawase, Atsushi Iwasaki

摘要:

当一方(公司或医院)可以向另一方(工人或医生)进行货币转移(提供工资)时,我们考虑与Hatfield和Milgrom的合同框架的匹配。在标准模式中,货币转移不受限制。但是,我们假设每家医院都有固定的预算,也就是说,每家医院分配给医生的工资总额是有限的。有了这个约束,稳定匹配可能不存在,并且很难检查其存在。为了处理不存在的,我们专注于近可行的匹配,可以超过每个医院的预算一定数量,我们引入了一个新的概念的兼容性。我们证明了相容性条件是契约匹配框架中存在近可行稳定匹配的充分条件。在对医院偏好的轻微限制下,我们提供了一种机制,该机制有效地返回了与每家医院分配的实际工资额接近可行的稳定匹配。通过牺牲防策略性,实现了预算超额的最佳可能界限。

英文摘要:

We consider the matching with contracts framework of Hatfield and Milgrom when one side (a firm or hospital) can make monetary transfers (offer wages) to the other (a worker or doctor). In a standard model, monetary transfers are not restricted. However, we assume that each hospital has a fixed budget; that is, the total amount of wages allocated by each hospital to the doctors is constrained. With this constraint, stable matchings may fail to exist and checking for the existence is hard. To deal with the nonexistence, we focus on near-feasible matchings that can exceed each hospital budget by a certain amount, and We introduce a new concept of compatibility. We show that the compatibility condition is a sufficient condition for the existence of a near-feasible stable matching in the matching with contracts framework. Under a slight restriction on hospitals' preferences, we provide mechanisms that efficiently return a near-feasible stable matching with respect to the actual amount of wages allocated by each hospital. By sacrificing strategy-proofness, the best possible bound of budget excess is achieved.
